DETAILED DESCRIPTION

Overview

With an increasing number of patients receiving care at home, there is a growing need for high-quality home monitoring and telehealth equipment. Accordingly, systems, methods, and apparatuses for improved patient monitoring are described. A patient monitoring device can be configured to provide fast and reliable physiological measurements in a variety of care settings, including, but not limited to, at the patient's home. In some aspects, the patient monitoring device includes a compact, standalone monitor with telehealth capabilities, as well as an intuitive interface for use at home.

The patient monitoring device can provide real-time patient data to clinicians, which promotes timely, patient-centric care. For example, the patient monitoring device can be configured for patient surveillance. The device or system can include one or more integrated or external cameras, microphones, and/or audio devices to facilitate one- or two-way patient-physician/caregiver communication. The patient monitoring device can be configured to incorporate live video chat capabilities, which can facilitate discussions (for example, regarding, treatment, medications, therapy, or the like) between patients and caregivers or health practitioners.

The patient monitoring device can be configured to measure various physiological parameters. For example, the housing of the patient monitoring device can be sized to fit one or more of various modules (or internal components) that provide different physiological monitoring capabilities. In various configurations of patient monitoring device, the patient monitoring device can include any combination of the one or more modules. For example, each of the configurations can include a baseline set of physiological monitoring capabilities. The addition of a module to a patient monitoring device can increase the physiological monitoring capabilities of the patient monitoring device. Non-limiting examples of configurations include a Pulse CO-Oximeter configuration, a non-invasive blood pressure (NIBP) configuration (for example, including one or more capabilities of the Pulse CO-Oximeter configuration, plus NIBP capabilities), and a capnography configuration (for example, including one or more capabilities of the Pulse CO-Oximeter configuration, plus capnography capabilities). Each configuration can include the same or a similar housing or sleek design. However, each of the one or more configurations can include a different faceplate (for example, for attaching different sensors or probes) and/or different internal components (for example, including different modules). Accordingly, portions of the housing can be interchangeable between the multiple configurations, thereby streamlining the manufacturing process by reducing the number or parts or molds required to manufacture the housing parts.

The patient monitoring device can include a sleek and continuous outer surface that is easy to clean and relatively free of crevices, holes, or surfaces that collect external contaminants. For example, the housing of the patient monitoring device can include multiple portions that are configured to attach primarily using internal connection features, while using limited or no screws or screw holes. In addition, the housing of the patient monitoring device can connect with a display using similar internal connection features and using limited or no screws or screw holes. By limiting a number of screw holes, the housing has fewer crevices, thereby reducing the amount of dirt or other contaminants that are stuck in the housing.

Temperature regulation of an electrical device has an influence on the device's service life, surface temperature, functionality, and electric and fire safety, among other things. To combat this, a device can include one or more ventilation holes or openings that allow air to exhaust through the patient monitoring device. In some cases, a ventilation hole can allow external contaminants to enter the device, which can affect the device's functionality. Accordingly, systems, methods, and apparatuses for improved ventilation of a patient monitoring device are described.

The patient monitoring device can include a vent cover that can be configured to cover a ventilation hole without occluding (or only partially occluding) the ventilation hole and/or configured to provide a stabilization feature to the patient monitoring device. The vent cover can couple to a patient monitor such that a ventilation hole is at least partially covered but is not occluded (or is only partially occluded) by the vent cover. When coupled to the patient monitoring device, the vent cover is swivelable (for example, when rotated by a user) and can be swiveled between various configurations.

In a first configuration, the vent cover can protect the ventilation hole(s) from external contaminants, while still allowing air to vent from the ventilation hole. For example, the patient monitor may be positioned proximate the patient such that patient fluids or other substances are likely to come in contact with the patient monitor. The vent cover can shield the ventilation hole to keep these substances from entering the patient monitor through the ventilation hole. In the first configuration, the vent cover can be swiveled parallel to a lengthwise axis of the device. In addition or alternatively, the vent cover can fit within indentions of a recess defined by the housing of the patient monitoring device such that an outer surface of the vent cover is at least partially flush, level, or even with an outer surface of the housing. This maintains the sleek, smooth design of the patient monitoring device, making it easier to clean and more portable. The first configuration is useful when moving or storing the patient monitoring device, or when the patient monitoring device is operating in a landscape mode for example.

In a second configuration, the vent cover can act as a stand or other stabilizing feature for the patient monitoring device. For example, the vent cover can be swiveled perpendicular to the first configuration and perpendicular to a lengthwise axis of the device. While in the second configuration, the vent cover can provide support and stability to the patient monitoring device. For example, the vent cover can aid in stabilizing the patient monitoring device, particularly when the device is in a portrait mode and is less stable.

In any of the above-discussed configurations, the vent cover can be configured such that it does not prevent a flow of air through the ventilation hole. Accordingly, the vent cover advantageously provides a multipurpose advantage of the having both a shielding configuration (for example, the first configuration) and a supporting or stabilizing configuration (for example, the second configuration), each of which allows ventilation through the ventilation hole.

Alternatively, the patient monitor may not include and/or the vent cover may not cover a ventilation hole. Rather, in the first configuration, the vent cover (which, in this example is sometimes referred to as a swivel foot) can simply be configured to be oriented parallel to a lengthwise axis of the device and fit within indentions of a recess defined by the housing of the device. Further, an outer surface of the swivel foot can be at least partially flush, level, or even with an outer surface of the housing. This maintains the sleek, smooth design of the patient monitoring device, making it easier to clean and more portable. The first configuration can be useful when moving or storing the patient monitoring device, or when the patient monitoring device is operating in a landscape mode for example. However, as described above, the swivel foot may or may not be protecting a ventilation hole. The second configuration of the swivel foot can correspond to the second configuration as described herein. For example, the swivel foot can be swiveled between perpendicular to the first configuration and perpendicular to a lengthwise axis of the device. The second configuration can provide support and stability to the patient monitoring device. For example, the swivel foot can aid in stabilizing the patient monitoring device, particularly when the device is in a portrait mode and is less stable.

Patient Monitoring System

FIG. 1 illustrates a schematic block diagram of an example patient monitoring system 100. As illustrated, the system 100 can include a patient monitoring device 102 in wired or wireless communication (for example, via Bluetooth, Wi-Fi, or cellular) with a combination of one or more of a blood pressure module 104, a pulse oximetry module 106, a capnography module 108, a video or camera module 110, one or more remote modules 114, and/or a monitoring station 112. The one or more modules 104, 106, 108, 109, or 110 can be integrated or combined with the patient monitoring device 102. Additional, fewer, or different modules can be in communication and/or incorporated within the patient monitoring device 102. Furthermore, any of the modules or stations can communicate with any of the other modules or stations.

The patient monitor 102 (sometimes referred to as a point-of-care device) can serve as a connectivity hub for any of various device that can be collectively referred to as remote modules 114. For example, the patient monitor can be wired or wirelessly, for instance via Bluetooth, aggregate data from each of a plurality of remote modules 114. The patient monitor 102 can communicate with or integrate data from one or more devices such as a weight scale, glucometer, spirometer, stethoscope, a capnograph (such as the EMMA™ Capnograph marketed and sold by Masimo Corporation of Irvine Calif. (“Masimo”)), a thermometer (such as the Caregiver marketed and sold by Masimo), a hemoglobin sensor (such as the Rainbow® DCI®-mini marketed and sold by Masimo), a pulse oximeter (such as the MightySat™ Rx marketed and sold by Masimo), etc.

The patient monitor 102 can advantageously include one or more ports for communicating with one or more sensors or sensor cables. For example, the patient monitor can include a port for communicating with a sensor configured to measure at least one parameter corresponding to oxygen saturation (SpO₂), pulse rate (PR), perfusion index (PI), total hemoglobin (SpHb®), methemoglobin (SpMet®), carboxyhemoglobin (SpCO®), oxygen content (SpOC®), oxygen reserve index (ORi®), pleth variability index (PVi®), acoustic respiration rate (RRa®), respiration rate from pleth (RRp™), fractional arterial oxygen (SpfO₂™), rainbow Pleth Variability Index (RPVi™), or signal quality. In addition or alternatively, the patient monitor 102 can include a port for communicating with a blood pressure sensor, such as a non-invasive blood pressure (NIBP) measuring device such as an arm cuff. In addition or alternatively, the patient monitor 102 can include a port for communicating with a capnography sensor (for example, a CO₂ sensor) so as to measure or determine parameters such as end-tidal carbon dioxide (etCO2), SpO2, NIBP, Predictive or Temporal Artery Temperature, Masimo Rainbow® parameters (for example, RRa™, SpCO®, PVi®), 3-Lead electrocardiogram (ECG) etc. The patient monitor 102 can include a port for communicating with a biopotential sensor, a respiratory rate sensor, or a glucose sensor. The patient monitor 102 can wirelessly communicate with sensor modules such as a blood pressure module, a pulse oximetry module, or a capnography module.

As a non-limiting example, the patient monitor 102 includes a sensor interface, a signal processor, and a transceiver. The patient monitor 102 receives a sensor signal associated with a sensor, for example, corresponding to a blood pressure module 104, pulse oximetry module 106, capnography module 108, remote module 114, or other module configured to measure one or more parameters which can be utilized for calculation or determination of physiological parameters. Depending on the sensor, the patient monitor 102 provides one or more drive signals to the sensor. The patient monitor 102 can receive (through wired or wireless connection) the sensor signal and can determine a conditioned signal The conditioned signal may be transmitted or further processed by a signal processor, such as buffering, digital filtering, smoothing, averaging, adaptive filtering and frequency transforms to name a few. The signal processor can derive a parameter or value responsive to the sensor signal. The resulting parameter signal may be a measurement calculated or derived from the conditioned signal, such as SpO₂, PR, Pi, blood pressure, or any of the physiological parameters described herein. In some instances, the parameter signal may be an intermediate result from which the above-stated measurements may be calculated or derived.

The patient monitor 102 may be battery powered or externally powered from an independent AC or DC power source. For example, the patient monitor 102 can include an internal rechargeable battery such as a lithium ion (Li-on) battery. The patient monitor can be configured to function for up to or more than 7 hours on a single battery charge. The battery can recharge from a state of no charge to a state of full charge in approximately 3 hours.

Patient Monitoring Device Configurations

FIGS. 2A-2C illustrate various example configurations of a patient monitoring device. As described herein, as compared to a baseline configuration (for example, the Pulse CO-Oximeter Configuration of FIG. 2A), some configurations of the patient monitoring device can allow for monitoring of one or more additional, fewer, or different physiological parameters.

Advantageously, one or more of the configurations illustrated in FIGS. 2A-C include a similar housing or chassis. Accordingly, portions of the housing can be interchangeable between the configurations. The back portions of the housings of each of the configurations can be identical or substantially similar. For example, the back portion 228 c of the configuration of FIG. 2C can be interchangeable with the back portion 228 a or 228 b of the configurations of FIG. 2A or 2B. However, in some cases, the back portions may differ. In addition or alternatively, front portions of the housing can be interchangeable between the configurations. For example, the front plate 224 c of the configuration of FIG. 2C can be interchangeable with the front plate 224 a/224 b of the configurations of FIG. 2A or 2B. However, in some cases, the front plates may differ. Having interchangeable portions of the housing or chassis can advantageously streamline the manufacturing process by reducing the number or parts or molds required to manufacture the housing parts. Furthermore, although the housings are similar or identical, the internal components of the multiple configurations can include similar, different, fewer, or additional components.

Pulse CO-Oximeter Configuration

FIG. 2A illustrates an example configuration of a patient monitoring device 200 a. As shown, the patient monitoring device 200 a can be a standalone monitor 200 a. The standalone monitor 200 a includes a housing 202 a, integrated display 222 a, faceplate 224 a, and sensor port 220 a. In some cases, this configuration is referred to as a Pulse CO-Oximeter configuration.

The sensor port 220 a can be configured to electrically connect with a sensing device, such as a pulse oximetry sensor, or corresponding cable. Based on a signal received from a sensing device, the patient monitoring device 202 a can determine one or more physiological parameters. For example, the physiological parameters can include, but are not limited to, oxygen saturation (SpO2), pulse rate (PR), perfusion index (Pi), and/or pleth variability index (PVi®). In addition or alternatively, the physiological parameters can include total hemoglobin (SpHb®), methemoglobin (SpMet®), carboxyhemoglobin (SpCO®), oxygen content (SpOC®), oxygen reserve index (ORi®), acoustic respiration rate (RRa®), respiration rate from pleth (RRp™), rainbow Pleth Variability Index (RPVi™), fractional arterial oxygen (SpfO2™), and/or or signal quality. In some cases, the patient monitoring device 202 a can be configured to determine some, if not all, of the physiological parameters listed above. For example, the patient monitoring device 202 a can be upgraded or downgraded to have the capability to monitor only particular parameters. In some cases, one or more calculations can be performed on the sensing device, and the patient monitoring device 202 a can receive one or more signals indicative of physiological parameters.

Noninvasive Blood Pressure (NIBP) Configuration

FIG. 2B illustrates an example NIBP configuration of a patient monitoring device 200 b. Similar to the patient monitoring device 202 a of FIG. 2A, the patient monitoring device 202 b includes a housing 202 b, an integrated display 222 b, a faceplate 224 b, and a sensor port 220 b. Furthermore, the patient monitoring device 200 b includes a port 218 for connecting a blood pressure sensing device. As shown, the faceplate 224 b can be different from faceplate 224 a of FIG. 2A, for example, to accommodate ports 220 b and 218. In some cases, this configuration is referred to as an NIBP Configuration.

The patient monitoring device 200 b can provide some or all of the capabilities of a Pulse CO-Oximeter, such as those described herein with respect to FIG. 2A. For example, the physiological parameters can include, but are not limited to, oxygen saturation (SpO2), pulse rate (PR), perfusion index (Pi), and/or pleth variability index (PVi®), total hemoglobin (SpHb®), methemoglobin (SpMet®), carboxyhemoglobin (SpCO®), oxygen content (SpOC®), oxygen reserve index (ORi®), acoustic respiration rate (RRa®), respiration rate from pleth (RRp™), rainbow Pleth Variability Index (RPVi™), fractional arterial oxygen (SpfO2™), and/or or signal quality. For example, the port 220 b can correspond to port 220 a of FIG. 2A, and the patient monitoring device 220 b can be configured to determine any of these various physiological parameters based on a signal received from a sensor attached to port 220 b.

In addition, the patient monitoring device 200 b can provide blood pressure monitoring capabilities. The patient monitoring device 200 b can be integrated with port 218 for connecting a blood pressure sensing device. For example, integrated port 218 can be configured to connect to blood pressure cuff (for example, via an inflation hose). The port 218 can be compatible with any of disposable or reusable blood pressure cuffs, for adult, pediatric, and/or neonatal patients.

The patient monitoring device 200 b can be configured to measure blood pressure between the range of 0 mmHg and 300 mmHg. The blood pressure measurements can provide blood pressure reading accurate within 1, 2, 3, 4, 5, or 10 mmHg. The patient monitoring device 200 b can be configured to provide “spot-check” blood pressure measurements, which can allow for a single, user-imitated measurement. The spot-check measurements can be taken at various times throughout the day. The patient monitoring device 200 b can be configured to routinely take blood pressure measurements (for example, at a desired interval), eliminating a need to do so manually. Furthermore, the patient monitoring device 200 b can be configured to continuously measure blood pressure for a desired duration, such as 5 or 10 minutes. As described in more detail herein, a value or display associated with any parameters or corresponding waveforms can be displayed on display 222 b.

Capnography Configuration

FIG. 2C illustrates an example Capnography configuration of a patient monitoring device 200 c. Similar to the patient monitoring device 202 a of FIG. 2A, the patient monitoring device 202 c includes a housing 202 c, an integrated display 222 c, a faceplate 224 c, and a sensor port 220 c. Furthermore, the patient monitoring device 200 c includes a connector 216 for connecting one or more Capnography-related sensors (for example, via a hose). As shown, the faceplate 224 b can be different from faceplate 224 a of FIG. 2A, for example, to accommodate ports 220 a and 218. In some cases, the faceplate 224 c can be different or the same faceplate as faceplate 224 b of FIG. 2B. This configuration can be referred to as a Capnography configuration or an ISA configuration.

The patient monitoring device 200 c can provide some or all of the capabilities of a Pulse CO-Oximeter, such as those described herein with respect to FIG. 2A. For example, the physiological parameters can include, but are not limited to, oxygen saturation (SpO2), pulse rate (PR), perfusion index (Pi), and/or pleth variability index (PVi®), total hemoglobin (SpHb®), methemoglobin (SpMet®), carboxyhemoglobin (SpCO®), oxygen content (SpOC®), oxygen reserve index (ORi®), acoustic respiration rate (RRa®), respiration rate from pleth (RRp™), rainbow Pleth Variability Index (RPVi™), fractional arterial oxygen (SpfO2™), and/or or signal quality. For example, the port 220 c can correspond to port 220 a of FIG. 2A, and the patient monitoring device 220 c can be configured to determine any of these various physiological parameters based on a signal received from a sensor attached to port 220 c.

The patient monitoring device 200 c can include an integrated ISA CO2 module and a capnography connector 216, which can enable the patient monitor 220 c to monitor aspects of CO2. For example, patient monitor can monitor end-tidal carbon dioxide (EtCO2) monitoring and can display numeric, trend, and/or waveform data on the display 222 c. In addition or alternatively, patient monitoring device 200 c can monitor fractional concentration of inspired carbon dioxide (FiCO2) and/or respiration rate (RR). The patient monitor 220 c can display on display 222C a capnogram waveform or a CO₂ trend waveform, among other data.

Integrated Display

FIG. 3A illustrates an example patient monitoring device 300 a. As shown, the patient monitoring device 300 a can include an integrated display 322. The display 322 can be customizable such that a user can choose which information to display on the display 322. For example, the user can choose to display one or more of various waveforms, trends, values, timelines, or other data related to a patient's physiological status. The display 322 can include touch screen capabilities. For example, a user can adjust a range of a displayed trend time by using intuitive fingers gestures (for example, pinching or spreading his or her fingers).

In some cases, the display 322 can display in portrait mode 302 or landscape mode 304, and can transition between display modes, for example, based on the orientation of the monitor 300 a. For example, the patient monitor can determine its orientation using a gyroscope or an accelerometer. Based on its determined orientation, the patient monitoring device 300 a can display in landscape or portrait mode. The display may display partially in portrait mode and partially in landscape mode. The display 322 can display in portrait mode when oriented vertically and can display in landscape mode when oriented on its side. A user can select landscape or portrait mode, which can cause the display to lock the display in the selected mode despite the orientation of the patient monitoring device 300 a.

FIG. 3B illustrates an example patient monitoring device 300 b. As described herein with respect to FIG. 2B, the patient monitoring device 300 b can be configured in an NIBP configuration. For example, the patient monitoring device 300 b can include a housing 202 b, an integrated display 222 b, a faceplate 224 b, a sensor port 220 b, and a port 218 for connecting a blood pressure sensing device 306 (for example, via hose 308). The blood pressure sensing device 306 can include a combination of one or more of a disposable or reusable blood pressure cuff that can be configured for adult, pediatric, and/or neonatal patient use.

Two-Way Consultation

FIGS. 4A-4B illustrate an example patient monitoring system configured for two-way consultation. The patient monitoring system can provide real-time virtual one- or two-way consultation using integrated video capabilities. For example, the patient monitoring system can include a high-definition camera, which can enable live, high-resolution video and audio feeds directly from a point-of-care device 400 to a central viewing station 402 or smart device, thereby allowing caregivers to provide on-demand care and/or support. The cameras can facilitate one- and two-way patient-caregiver communication. The one- or two-way consultation (sometimes referred to as videoconferencing) advantageously provides a medium for on-demand care and aids in proactively determining when an in-person visit is desired or necessary. For example, one-way, surveillance monitoring can enable a caregiver to observe patient movements and listen to breathing for virtual assessment without disturbing the patient.

The patient monitoring system can cause a display to display in real-time a video or image of a patient 428 a, 428 b and/or a real-time video or image of a caregiver 430 a, 430 b. The videos or images can include high-definition video (for example, 1080i, 1080p, 4 k, etc.), and in some cases, the cameras can be integrated directly into the patient monitoring device 400, eliminating the need to purchase additional modules or infrastructure. In some cases, the system utilizes a video surveillance system, such as Masimo's SafetyNet Surveillance.

The patient monitoring device 400 can be configured to facilitate the transmission of patient data and/or the transmission of live video conferencing. For example, the patient monitor can share video and/or patient data to one or more of clinicians, caregivers, electronic medical records, or a monitoring station 402. Accordingly, the patient monitoring device 400 can advantageously serve as an integrated solution for patient data gathering and/or transmission. In some cases, the system can utilize an existing hospital IT network and can provide viewing of images in the same care area. Accordingly, the system can provide for real-time video and/or audio communication that can improve the quality and safety of patient care.

The real-time video images of a patient's room and/or a monitoring station can be gathered using, for example, an integrated or remote camera. For example, a camera associated with patient monitor 400 can deliver a high-resolution, high-frame rate video feed to the patient monitoring device 400 or a viewing station 402. Similarly, a camera associated with viewing station 402 can deliver a high-resolution, high-frame rate video feed to the patient monitoring device 400 or a viewing station 400. In some instances, the system can include an external mechanical lens cap lets the patient or his visitors disable or cover the camera at any time.

In addition or alternatively, the video feed or images presented at the patient monitoring device 400 or a viewing station 400 can include one or more physiological parameters. For example, the one or more physiological parameters can be overlaid on and/or positioned around (for example, in a separate window) the live video feed such that the patient and/or caregiver can view both the video feed and the physiological parameters. In some cases, the physiological parameters can be presented on a separate display that is different from the display presenting the real-time video images.

Vent Cover

FIG. 5 illustrates an example vent cover for a patient monitoring device. The vent cover 500 can include a body 524, an extension member 538, and an engagement member 530. The extension member 538 can extend between the body 524 and the engagement member 530.

The body 524 can be relatively flat and can have a length which is longer than its width. For example, the length of the body 524 can be about 1.25, 1.5, 1.75, 2, 2.25, 2.5, 2.75, 3, 3.5, 4, 4.5, or 5 times the width of the body 524. Alternatively, the length of the body 524 can be approximately equal to the width of the body 524. The length and/or width of the body 524 can depend on the size of the patient monitoring device to which it will be attached. The body 524 can have a rectangular, curved rectangular or other shape. The body 524 can have a relatively constant length and/or width. Alternatively, the width and/or length may not be constant across the body 524. For example, a middle of the body 524 may be thin or thick relative to the outer edges of the body 524.

The extension member 538 extends away from the body the extension member 538 can extend from the body 524 at an angle of roughly 90° degrees (for example, 90° from a longitudinal plane of the vent cover 500). However, other angles are possible, such as 30°, 40°, 50°, 60°, 70°, 80°, 100°, 110°, 120°, 130°, 140°, 150°, 160° (+/−a few degrees).

The extension member 538 can be generally cylindrical or have substantially rounded sides, for example, to facilitate rotation of the vent cover 500 about an axis of the extension member 538. However, it should be understood the extension member can have any suitable shape. The extension member 538 can include one or more substantially flat sides which can advantageously limit undesired rotation of the vent cover 500. For example, a portion of the vent cover can be disposed within a hole (for example, hole 616 of FIG. 6 ) of a patient monitor such that the extension member 538 is framed by the exterior of the hole. The extension member 538 may have a flat side which corresponds to a flat portion of the hole. When the flat portions are aligned, the vent cover 500 can be in a desired configuration. Thus, the flat side may advantageously provide a locking feature which can limit movement (for example, rotation) of the vent cover 500.

Although illustrated as an extension from the center of the vent cover 500, the extension member 538 can extend from or be attached to any location on the vent cover 500. For example, the extension member 538 can extend from end 582 or end 584 or a corner of the body 524. Alternatively, the vent cover 500 can include two extension members 238, which can extend from each end 582, 584 of the body.

The extension member 538 can be substantially rigid or flexible. For example, the extension member 538 may be configured to bend relative to the body 524 or the engagement member 530. The extension member 538 includes a plurality of ribs 540 or rib-like features. The ribs can provide additional support or flexibility to the extension member 528 of the vent cover 500. In addition, the ribs 540 can define a plurality of cavities 542 between the ribs 540. In addition to providing room for the ribs 540 to flex, in some cases, the cavities 542 can provide a pathway for air to escape or enter the patient monitoring device while the vent cover 500 is attached to a patient monitoring device. The cavities 542 can permit air to flow through or around the vent cover 500, thereby facilitating exhaust of the patient monitoring device.

The vent cover 500 can include one or more feet 520, 522 disposed on the bottom of the body 524. The feet can be rubber or composed of any suitable material. The feet can provide a non-slip and/or non-scratch surface to the vent cover 500. The feet 520, 522 can be retractable, foldable, or otherwise adjustable to provide a more compact or sleek appearance, for example, when position in the first configuration. The feet 520, 522 can extend the width of the vent cover. Alternatively, the feet 520, 522 can be thinner or wider than the vent cover. Although illustrated as having two feet 520, 522, the vent cover can include fewer or more feet. In some cases, the vent cover does not include any feet.

The vent cover 500 can be generally composed of metal alloys, plastic, or other suitable material and can be made by conventional machining and metal fabrication techniques, plastic fabrication techniques, and finishing processes including but not limited to milling, lathing, electro discharge and welding, injection molding, powder coating and painting. The vent cover 500 can be coated with one or more coatings, including but not limited to plastic, rubber, powder coat and paint or any combination thereof. The combination of the vent cover 500 and a housing of a patient monitoring device (as described herein) can include multiple parts assembled or disassembled and delivered to its intended user. For example, an intended user can insert engagement member 530 of the vent cover 500 into or remove it from an aperture defined by the housing.

Patient Monitoring Device without Vent Cover

FIG. 6A illustrates an example a patient monitoring device configured to couple to the vent cover of FIG. 5 . As illustrated, the patient monitoring device 600 can include a display 608, a housing 602, a carrying handle 604, a protrusion 610 (sometimes referred to as a foot), and a section 606 for coupling and/or interfacing with a vent cover, such as vent cover 500 of FIG. 5 .

The patient monitoring device 600 can be configured to sit upright (sometimes referred to as portrait mode) such that it rests on a bottom side. The housing 602 can include one or more protrusions 610 upon which the patient monitoring device 600 can be set. Further, the patient monitoring device 600 can include section 606 for interfacing with a vent cover, which may also aid in keeping the patient monitoring device upright.

The patient monitoring device 600 can include a carrying handle 604. For example, the housing 602 can define an aperture and the carrying handle 604 can be defined as the portion of the housing 602 between the aperture and the top of the patient monitoring device 600. In some instances, the aperture is approximately sized to fit a palm of a user's hand such that the user can grasp the handle by inserting his fingers into the aperture. The aperture can be larger, smaller, or about the size of the palm of a user's hand. For instance, the aperture can be sized to fit a user's arm such that the patient monitoring device 600 can be carried by, for instance, inserting a user's forearm into the aperture. The handle 604 can be advantageously positioned near the top of the patient monitoring device 600 to allow for easy carrying. However, it should be noted that the handle 604 can be positioned in any suitable location on the patient monitoring device 600.

FIG. 6B illustrates a detail view of the section 606 for coupling and/or interfacing with a vent cover. As shown, the section 606 includes a plurality of indentations 630, 638 and a defined hole 616. In addition to acting as a connection point for a vent cover, the hole 616 can act as a ventilation hole to allow airflow though the patient monitoring device. In some cases (as illustrated in FIG. 8A), the recess 606 can include one or more ventilation holes 802 for additional airflow.

Referring to FIGS. 5 and 6B, the vent cover 500 can be coupled to the patient monitoring device 600 through hole 616 such that the hole encompasses the extension member 538. For example, the engagement member 530 can be inserted into hole 616. The engagement member 530 can include one or more flexible wings 532, 534 that cause the engagement member 530 to extend wider than the hole 616. For example, the engagement member 530 can be fit into the hole 616 by flexing or bending the wings 532, 534 (for example, towards the body 524) such that the width of the engagement member 530 is reduced and the engagement member 530 can fit into the hole 616. Upon insertion of the engagement member 530 into the hole 616, the flexible wings are configured to un-flex and act as an anchor to prevent the vent cover 500 from uncoupling from the housing 606. However, it will be understood that the vent cover 500 can be coupled to the patient monitoring device in various ways, such as during assembly of the patient monitoring device.

As illustrated, the housing 602 can define a plurality of raised indentions 642 between indentations 630, 638. The raised indentations 642 can function to stabilize the patient monitoring device by providing support to the vent cover 500 during the second configuration. In addition or alternatively, the raised indentions 642 can function as a locking feature which provides a barrier between configurations.

The indentations 630 and/or 638 can function as an exhaust feature. For example, while in a first configuration, indentations 638 may have a greater depression (for example, deeper) than the body of the vent cover 500. Thus, a space can exist under the vent cover 500, which can permit ventilation. For example, the space can provide an air passageway into the interior of the patient monitoring device. Similarly, while in a second configuration, indentations 630 may have a greater depression (for example, deeper) than the body of the vent cover 500. Thus, a space can exist under the vent cover 500, which can permit ventilation.

First Configuration

FIGS. 7A-7C illustrate an example patient monitoring device configured in a first configuration, according to some embodiments. The vent cover 500 is configured to protect one or more air vents (for example, vents 802 of FIG. 8A) from external contaminants without occluding (or only partially occluding) the air vents. Accordingly, the vent cover 500 can protect the patient monitoring device from contaminants while also permitting cooling/exhaust, for example, through the air vents. As described herein, the housing 602 includes section 606 which can be one or more depressions, slots, notches or other indentations in the housing 602. The section 606 can be sized to fit the vent cover 500. For example, the section 606 can be the approximately the same shape as (for example, slightly larger than) the body 524 of the vent cover 500 such that the vent cover 500 can fit within the section 606. The vent cover can protect one or more vents of the patient monitor from external contaminants.

FIG. 7A illustrates a bottom view of the housing 602 coupled to the vent cover 500 while the vent cover is in a first configuration. While in the first configuration, the patient monitor is in a more compact state as compared to the second configuration. For example, indentations 630 can be sized to fit the vent cover 500, and, when in a first configuration, the vent cover 500 can fit at least partially within indentions 630 such that an outer surface of the vent cover is at least partially flush, level, or even with an outer surface of the housing 602.

FIG. 7B illustrates a side view of a patient monitoring device 100 while the vent cover 500 is in a first configuration, according to some embodiments, and FIG. 7C illustrates a detail view of the recess 606 of the side view of FIG. 7B. As illustrated in FIG. 7C, the vent cover 500 can be substantially flush, level, or even with the outer surface of the housing 602. As such, the first configuration advantageously provides a sleek design with a continuous outer surface that is easy to clean and reduces crevices or surfaces that are difficult to clean. In addition, the sleek configuration permits a user to easily carry or store the patient monitoring device (for instance, using carrying handle 164) without having to continuously avoid or worry about catching or snagging the vent cover on a passing object.

When in the first configuration, the vent cover 500 can at least partially cover the one or more ventilation openings, such as ventilation openings 802 of FIG. 8A. However, because of the shape of the vent cover 500 and/or the section 606, a ventilation hole 702 remains un-occluded (or is only partially occluded), such that air can continue to be vented into or out of the patient monitoring device 100. For example, the ventilation hole 702 can provide a passageway into the patient monitoring device and thereby can act as a ventilation hole, despite the fact that the vent cover 500 is occluding ventilation opening 802.

Second Configuration

FIGS. 8A-8C illustrate an example patient monitoring device configured in a second configuration, according to some embodiments. FIG. 8A illustrates a perspective view of the patient monitoring device 100. The second configuration of the vent cover 500 can be utilized to provide support to the patient monitoring device 100. For example, the vent cover 500 can be configured to provide a stabilization feature to the patient monitoring device 100 that can keep the patient monitoring device upright.

While in the second configuration, the vent cover 500 and/or the protrusion 610 are configured to aid in supporting the patient monitoring device 100 while it is in an upright position. For example, the protrusion 118 can support the front of the patient monitoring device and/or the vent cover 500 can support the rear of the patient monitoring device. During the second configuration, the vent cover 500 is oriented such that its ends protrude past edges of the housing 602 and provide lateral support to the patient monitoring device 100. The lateral support can limit wobbling and aid in keeping the patient monitoring device 100 in an upright position.

In a second configuration, the vent cover 500 can be oriented (for example, by rotation) such that it is substantially perpendicular to an axis corresponding to the length of the patient monitoring device. The length of the vent cover 500 can vary across embodiments. For example, the vent cover 500 can be longer (for example, 1.5, 2, 2.5, or 3 times longer) than the width of the side of the housing 602. Alternatively, the vent cover 500 can be approximately the same length or is shorter than the width of the side of the housing 602.

The vent cover 500 can provide support to the entire patient monitoring device or can support only a portion of the patient monitoring device. For example, the vent cover 500 can be distal a front portion of the patient monitoring device such that, when in a second configuration, it can support a back end of the patient monitoring device.

FIG. 8B illustrates a side view of the patient monitoring device 100, and FIG. 8C illustrates a detail view of section 606 of FIG. 8B. As shown, the section 606 is defined by the plurality of indentations 630, 632. The curved indentation 638 is shaped such that one or more ventilation holes 802 exist between the housing 602 and the vent cover 500. The ventilation hole 802 provides a passageway into the interior of the housing 602 such that air can flow into or out of the patient monitoring device. Accordingly, the ventilation hole 802 advantageously acts as a ventilation opening, thereby providing additional cooling capabilities to the patient monitor.

Transitioning Between Configurations

The vent cover 500 can be rotated to transition from one configuration (for example, first configuration) to another configuration (for example, second configuration). The configurations may be separated by 45°, 90°, 180° or another angle, and the user can rotate the vent cover 500 about the extension member 538. For example, the extension member 538 can be positioned in the hole 616 of the patient monitor. In some cases, during the transition between a first configuration and a second configuration, the vent cover 500 is in an intermediate configuration, which can be somewhere between first and second configurations. The intermediate configuration can be merely the configuration of the vent cover 500 while it is transitioning from either the second configuration to the first configuration or the first configuration to the second configuration. Alternatively, the intermediate configuration can provide some or all of the functionality of the second configuration and/or the first configuration.

While in the first configuration, the vent cover 500 can be difficult to grab because the vent cover 500 can be positioned within the section 606. Accordingly, to increase the ease of transitioning the vent cover 500 between configurations, the section 606 of the housing 602 may include one or more indentations around the vent cover 500, such as indentations 630. By providing a notch or indentation (such as indentations 630 or 638) in the housing 602, a user can more easily grab the sides of the vent cover 500 and rotate to a new configuration. For example, Indentations 630 and 638 can function as finger slots that permit a user to grasp the body of the vent cover 500. For example, indentations 630 or 638 can recess into the housing such that one or more edges of the vent cover 500 are visible and/or accessible when the vent cover is in the first configuration and/or the second configuration.

The vent cover 500 and/or the housing 602 can include a locking feature which can function to reduce or prevent rotational movement of the vent cover 500. For example, the locking feature can include one or more of raised indentations 642. For instance, the raised indentations 642 may provide some resistance to initial rotation of the vent cover 500. The shape of the extension member 538 and/or the shape of the hole 616 can additional or alternatively function as the locking feature. For example, a locking mechanism can be activated (for example, locked) while the vent cover 500 is in a stabilization configuration such that the vent cover 500 cannot be incidentally rotated or re-positioned. In some instances, a locking feature can provide extra stability to the vent cover 500 or housing 602, for instance, while the vent cover 500 is supporting the patient monitoring device. The locking feature can also or alternatively be engaged when the vent cover 500 is in a first configuration. In some cases, the locking feature can be deactivate or unlocked while the vent cover 500 is changing configurations, such as when the vent cover 500 is in an intermediate configuration.

The vent cover 500 can transition between configurations while coupled to the patient monitoring device 100. For example, the vent cover 500 can be rotated, twisted or swiveled to transition between configurations. The vent cover 500 can be rotated about an axis of the extension member 538. The extension member axis can be approximately perpendicular to the body 524 of the vent cover 500. One or more configurations can be separated by approximately 45, 90, 135, or 180 degrees of rotation of the vent cover 500. For example, if the vent cover 500 is configured in a first configuration, then the vent cover 500 will transition into a second configuration upon rotation of the vent cover approximately 90°. The vent cover 500 can transition between configurations through a clockwise or counterclockwise rotation. Alternatively, the vent cover 500 can be permitted only to rotate in a single direction. In some cases, the vent cover 500 can be at least partially rotationally symmetric. That is, the configuration of the vent cover 500 will be in the same if rotated in either direction approximately 180°.

Although described herein as a vent cover, in some cases the vent cover 500 may not cover a ventilation hole. Rather, the vent cover 500 (sometimes referred to as a swivel foot) can be configured to function as a stabilizing feature. For example, as described herein, the swivel foot 500 can be swivelable (for example, when rotated by a user) and can be swiveled between various configurations. In a first configuration, the swivel foot 500 can be swiveled parallel to a lengthwise axis of the device. In the first configuration, the swivel foot 500 can fit within indentions of a recess defined by the housing of the patient monitoring device such that an outer surface of the swivel foot 500 is at least partially flush, level, or even with an outer surface of the housing. This maintains the sleek, smooth design of the patient monitoring device, making it easier to clean and more portable. The first configuration can be useful when moving or storing the patient monitoring device, or when the patient monitoring device is operating in a landscape mode for example. In a second configuration, the swivel foot 500 can be swiveled perpendicular to the first configuration and perpendicular to a lengthwise axis of the device. The second configuration can provide support and stability to the patient monitoring device. For example, the swivel foot 500 can aid in stabilizing the patient monitoring device, particularly when the device is in a portrait mode and is less stable.

Smooth and Easy to Clean Design

The disclosure advantageously provides for a patient monitoring device which is sleeker and easier to clean than conventional patient monitoring devices that have many crevices and holes. Specifically, the patient monitoring devices disclosed herein can include a housing configured to connect together and to house a display using a limited number of screws while still allowing the devices to be serviceable. By limiting a number of screw holes or other holes or crevices, the housing can have fewer crevices, which can reduce the amount of dirt or other contaminants that are stuck in the housing.

FIGS. 9-10 illustrate example internal structural components of a patient monitoring device. In some instances, the shape or location of a connection feature can be dependent on its position, function, etc. within the patient monitoring device. For example, the connection feature can include a simple t-shaped design that can fit in a corresponding t-shaped hole, functioning similar to a lock and key. Alternatively, the connection feature can include a peg 952 or other insert 954 which can connect to a corresponding hole. The connection feature can be tall, such as connection features 944, 948, which can, for example, provide structural support within the patient monitor. In some instances, the connection feature can be beveled or include a slot (such as connection feature 1060 of FIG. 10 ) to, for instance, provide a slot for a cable.

FIGS. 11A-11F illustrate a plurality of example connection features which can be utilized to connect portions of housing together, thus obviating or reducing the number of screws required for connecting the housing portions. As illustrated in FIG. 12 , which is described in more detail below, each of the connection portions can have corresponding connection portions that mate together, for example, by inserting one into the other or snapping together. It should be noted that while FIGS. 11A-11F illustrated a plurality of connections features, this is not intended to illustrate an exhaustive list. For example, a connection feature can include a lock and key or one more elements that can be twisted to hold the chassis/housing together. One or more additional features can be utilized to connect the portions of the housing together, such as connecting the display housing to a side portion of the housing.

FIGS. 12A-12B illustrate example connections between a display housing 1262 and a first side housing 1255. The first side housing 1255 includes a plurality of connection features, such as connection features 1246, 1248, and 1250. Similarly, the display housing 1262 includes a plurality of corresponding connection features, such as connection features 1270, 1272, 1274, and 1278.

As shown by the dashed lines in FIG. 12A, the display housing 1262 can be connected to the first side housing 1255 via the mating of a plurality of connection features. For example, connection feature 1270 (an aperture) can be aligned with connection feature 1248 (an insert). Similarly, connection features 952, 954 (inserts), as illustrated in FIG. 9 , can be aligned with connection features 1272, 1274 (apertures), respectively. In addition, connection features 1278 (insert) can be inserted or snapped into connection features 1250 (slots). The display housing 1262 can be also connected to a second side housing in the same or similar manner. As shown, the mating arrangements of the housing portions allow the front housing 1262 to be held in place securely without using screws (or, in some cases, only using a limited number of screws), which reduces the number of crevices that must be cleaned.

FIG. 13A illustrates example connections between a second side housing 1396, the display housing 1262, and the first side housing 1255. As described herein, the display can connect to the side housings 1396, 1255 without using screws, or only using a limited number of screws, which reduces the number of crevices that must be cleaned. Similarly, the side housings 1396, 1255 can connect using no or a limited number of screws. In some cases, the screws connecting the side housing can further secure the display housing within the patient monitoring device. In this example, the first side housing 1255 and the second side housing 1396 are connected using four screws 1370 a, 1370 b, 1370 c, and 1370 d are utilized. However, various other numbers of screws can be used.

In some cases, the housing can include a plurality of connection points 1280 a, 1280 b, 1280 c, and/or 1280 d for mounting the patient monitoring device 1300, such as to a cart or wall. When the patient monitoring device 1300 is not mounted, one or more plugs can be inserted into the connection points 1380 a, 1380 b, 1380 c, and/or 1380 d to reduce the number of open crevices. Similarly, one or more plugs, such as plug 1282 c or 1282 d, can be inserted into the screw holes to further reduce the number of open crevices.

FIG. 13B illustrates a detailed view of the seam 1390 or connection between the housing portions. As illustrated, when the front housing 1262, the first side housing 1255, and the second side housing 1396 are connected together, a tight seam 1390 exists between the housing portions to maintain to sleek and limited crevice design of the patient monitoring device 1300. In addition, the front portion of the patient monitoring device 1300 advantageously has few or no indentations, for example, with the exception of ports 1318 and 1390. In many instances, during use, the display faces the patient. As a result, the screen and the periphery of the screen are likely to collect or accumulate patient fluids. By reducing or limiting an amount of crevices of the patient monitoring device, especially the front portion and periphery of the front portion, fluids from the patient (or other fluids) cannot or are less likely to enter or be stuck in or on the patient monitoring device.

Flow Diagrams

FIG. 14 is a flow diagram illustrative of an example of a routine for reconfiguring a vent cover. One skilled in the relevant art will appreciate that the various blocks described herein with reference to FIG. 14 can be implemented in a variety of orders. For example, a user can implement some blocks concurrently or change the order as desired. Furthermore, it will be understood that fewer, more, or different blocks can be used as part of the routine 1400.

At blocks 1402 and 1404, a patient monitoring device and a vent cover are provided. The vent cover and patient monitoring device can include any of the features as described herein. For example, the housing can define a recess and can further define one or more ventilation holes in the recess. The vent cover can be coupled to the housing, such as at the recess. For example, when coupled together, the vent cover can reside within or partially within the recess. The patient monitoring device and vent cover can be provided as one unit or can be provided separately. For example, where the patient monitoring device and vent cover are provided separately (for example, not attached), the routine 1400 can further include coupling the vent cover to the patient monitoring device. The coupling can include inserting the vent cover into the hole 616 of the patient monitoring device. In some cases, coupling can further include flexing the wings of the engagement member, inserting the engagement member into a hole of the patient monitoring device, and/or un-flexing the wings of the engagement member.

At block 1406, the vent cover can be rotated (for example, by a user) to the second configuration. As described herein, in the second configuration, the vent cover can be act as a stand or other stabilizing feature for the patient monitoring device. For example, the vent cover can be swiveled or rotated perpendicular to the first configuration and perpendicular to a lengthwise axis of the device. While in the second configuration, the vent cover can provide support and stability to the patient monitoring device. For example, the vent cover can aid in stabilizing the patient monitoring device, particularly when the device is in a portrait mode and is less stable. In this second configuration, the vent cover can be configured such that it does not prevent a flow of air through the ventilation hole.

At block 1408, the vent cover can be rotated (for example, by a user) to the first configuration. As described herein, in the first configuration, the vent cover can protect the ventilation hole(s) from external contaminants, while still allowing air to vent the ventilation hole. For example, the patient monitor may be positioned proximate the patient such that patient fluids or other substances are likely to come in contact with the patient monitor. The vent cover can shield the ventilation hole to keep these substances from entering the patient monitor through the ventilation hole. In the first configuration, the vent cover can be swiveled parallel to a lengthwise axis of the device. In addition or alternatively, the vent cover can fit within indentions of a recess defined by the housing of the patient monitoring device such that an outer surface of the vent cover is at least partially flush, level, or even with an outer surface of the housing. This maintains the sleek, smooth design of the patient monitoring device, making it easier to clean and more portable. The first configuration is useful when moving or storing the patient monitoring device, or when the patient monitoring device is operating in a landscape mode for example. In this first configuration, the vent cover can be configured such that it does not prevent a flow of air through the ventilation hole.

Throughout the process 1400, the vent cover can be configured such that it does not prevent a flow of air through the ventilation hole. Accordingly, process 1400 demonstrates the multipurpose advantage of the vent cover in that is can provide both a shielding configuration (for example, via the first configuration) and/or a supporting or stabilizing configuration (for example, via the second configuration).

Depending on the embodiment, certain acts, events, or blocks, identified in process 1400 can be performed in a different sequence, can be added, merged, or left out altogether (non-limiting example: not all described blocks are necessary). For example, any one of blocks 1406 or 1408 can be omitted. Moreover, block 1408 can be performed prior to block 1408,

Furthermore, in some cases, the patient monitor may not include and/or the vent cover may not cover a ventilation hole. Rather, in the first configuration, the vent cover (which, in this example is sometimes referred to as a swivel foot) can simply be configured to be oriented parallel to a lengthwise axis of the device and fit within indentions of a recess defined by the housing of the device. Further, an outer surface of the swivel foot can be at least partially flush, level, or even with an outer surface of the housing. This maintains the sleek, smooth design of the patient monitoring device, making it easier to clean and more portable. The first configuration can be useful when moving or storing the patient monitoring device, or when the patient monitoring device is operating in a landscape mode for example. However, as described above, the swivel foot may or may not be protecting a ventilation hole. The second configuration of the swivel foot can correspond to the second configuration as described herein. For example, the swivel foot can be swiveled between perpendicular to the first configuration and perpendicular to a lengthwise axis of the device. The second configuration can provide support and stability to the patient monitoring device. For example, the swivel foot can aid in stabilizing the patient monitoring device, particularly when the device is in a portrait mode and is less stable.
